With reliable measurement, it’s clear. Without it, you’re deciding blind. Sample data; they don’t correspond to any client.

Does any of this sound familiar?

💸

I pay for clicks and no customers come in

I don’t know which campaigns generate real leads and which just burn budget.

📊

I don’t know if my data is reliable

GA4 shows numbers that don’t add up and my forms aren’t tracked properly.

📉

My organic traffic has dropped

I’ve lost visits from Google and I don’t know whether it’s a technical, content or competition problem.

Hi, I’m Gema

I’m a freelance analytics and lead-generation consultant in Barcelona. I work with service businesses that invest in SEO and Ads but aren’t sure what brings them customers.

I like solving complex problems and finding answers where others only see noise. I’m not interested in vanity metrics or generic “monthly report” templates that say nothing useful.

My approach is practical: I detect real SEO problems, prioritize the actions with the most impact and make decisions based on data, not intuition. No smoke and mirrors, no empty promises and no lock-in if you’re not seeing results.

With me you don’t need to build a marketing team or hire different vendors for every task. I set up and manage your advertising campaigns, get your analytics properly built so you know where your customers come from, install the technical tracking needed so that data is reliable (not estimates), and deliver results in reports you can understand at a glance, without jargon or endless tables.

Frequently asked questions

Who is the SEO consultant and what services does she offer?

I’m Gema Calderón Sayoux, a freelance SEO consultant in Barcelona with more than 5 years of experience. I offer SEO audits and strategy, Google Ads (SEM) campaign management, link building and advanced analytics (GA4, Google Tag Manager, Looker Studio). You work directly with me, with no middlemen and no need to hire different providers.

How long does it take for your website to rank on Google?

It depends on your website’s technical state, your competition and how difficult the target keywords are. As a rough guide, the first movements are usually seen between 3 and 6 months, with consolidated results on more competitive keywords between 6 and 12 months. In the initial audit I give you a realistic estimate for your specific case, not a generic number.

What aspects of a website do I work on as an SEO consultant?

I work on technical SEO (speed, indexing, crawling), on-page SEO (content, heading structure, keywords) and off-page SEO (link building and authority). I also set up analytics and tracking to measure real results, and I optimize for local SEO and for appearing in AI-generated results.

Do you work with local businesses such as locksmiths or plumbers?

Yes. It’s one of the sectors I want to focus on now: urgent-service businesses where showing up first on Google means getting the call instead of losing it to the competition.

Shall we start by finding out what’s going on with your lead generation?

Tell me about your situation and I’ll get back to you. No strings attached: the first step is understanding your case.
